grid
structured cartesian grid. cells are uniform-spaced in each direction.
fluid properties
solver settings
SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) with collocated grid and Rhie-Chow interpolation.
boundary conditions
wall = no-slip (set velocity). inlet = Dirichlet velocity. outlet = zero-gradient (Neumann). symmetry = slip wall.
north (y = Ly)
south (y = 0)
west (x = 0)
east (x = Lx)
initial conditions
uniform initial field values for velocity and pressure.
